BLE connection problem

DragonAnger

Hi,

I'm using sdk12.3.0 ble_app_uart.

My problem is BLE connection.

Sometimes(almost 50%)I tried to connect BLE but fail and I have to connect again.

I don't know why.

This image is messages that I captured when connection failed.

What is the problem?

Thank you for reading my question!

    Is this a custom board or the nRF51-DK ? On the nRF51-DK, the on-board Segger J-link programmer that have the Virtual COM port via UART, uses pin 9 and 11. So if you are using the DK you won't be able to send and receive data from the PC terminal if you change the pins to 5 and 6.

    So if you use the default pin numbers(11 and 9), then you don't get the Device is not supported message ?
